Film Showing - Niles Johnson will screen his short film on the 7-dimensional exotic sphere

In 1956 John Milnor startled the mathematical community byconstructing smooth 7-dimensional manifolds that are homeomorphic butnot diffeomorphic to the standard seven-sphere. His discovery opened anew branch of research in topology and won him the Fields Medal in1962. In this animation we present Milnor's construction and give away of visualizing these manifolds.
